9 Claims.

Good farm stock must be well housed and this cannot be done Without good buildings having strong, closely fitting, well insulated doors. Farm building doors are exposed to all kinds of 6 weather and they must therefore be insulated and be water and sweat proof. Generally stated the object of the present invention is to provide a door which is especially suited to barns and poultry houses, wherein the door is strong,

durable, light, selfsealing, is insulated and can Y be manufactured at 10W cost.

A further object is to provide a steel armored door which cannot accumulate moisture on the inside and is proof against rain being driven by high Winds into lthe interior or under the sheathing.

Another object of my invention is4 to provide frame members which may be easily and quickly assembled over the door panel and secured thereto.

It is further an object to not only prevent water or moisture from entering or forming on the interior of the door, but also provide air channels and moisture drains or drips, thus t0 doubly insure against interior moisture.

Farm buildingl doors are roughly handled and must therefore be strong and durable. An object of the present invention is to provide a door which is impervious to the Weather and rough handling and also provide a simple strong hinge supporting means whereby suitable bolts may be used to secure the hinges to a reinforced part of the panel.

Still another object is to provide a door which may, without changing the essential parts, be made fully or semi-insulated, or I may dispense with the insulating material entirely by providing instead a dead air space only as an insulating medium.

These objects are accomplished by means of a novel frame, novel flashing, novel front sheathing and suitable air spaces and pockets as will hereinafter appear.

To these and other useful ends my invention resides in features of construction and combinations thereof or their equivalents as hereinafter set forth and claimed and shown in the accompanying drawings in which- Fig. 1 is a front elevation of one form of my invention.

1 Fig. 2 is a vertical section taken on line 2-2 of' Figure 1.

Fig. 3 is a transverse section taken on line 3-3 of Figure 1.

(Cl. 18S-116) Fig. 4 is an enlarged fractional vertical section taken on line 4-4 of Figure l.

Fig. 5 is an enlarged fractional horizontal section taken on line 5 5 of Figure 1.

Fig. 6 is an enlarged fractional section taken on line S- of Figure l.

Fig. '7 is an enlarged horizontal section of the front sheathing taken on line 'l--l of Figure l.

As thus illustrated my improved door comprises a front sheathing which, in its entirety, is designated by reference character A and a rear sheathing i E. sheathing A is provided with widely spaced and relatively large projections l2 the apexes of which are slightly rounded as at i3, the base of the projections being rounded as at lli.

I provide a number of shallow V shaped corrugations l5 having straight sides and sharp apexes as at i@ thus to stifien the portion of the sheathing A which lies between projections l2. These projections and corrugations, in addition to giving the front of the door a pleasing appearance, stiifen the door and form dead air channels for a purpose which will hereinafter appear. Projections l2 terminate as at Il.

By referring now to Figure 4 it will be noted that sheathing A extends slightly outward at its bottom beginning as at i8, the bottom terminating as at le leaving an elongated 4V shaped pocket 22 the base of which terminates slightly below the bottom of the insulating sheet and Wood cleats as will hereinafter appear.

I provide three or more types of llers for my improved door, one being illustrated in Figures 2, 3, 4 and 5, wherein insulation 25 may be made in a single sheet having a length and width preferably slightly greater than rear sheathing H. Front sheathing A is also slightly narrower than member 25 and does not extend quite to the top or sides of member 25. The bottom of member A it will be noted, extends a considerable distance below the bottom of member 215, (see Figure i).

I provide a number of transverse wood cleats 2S each extending for the width of member 25 and filling the space between 25 and member A. In the full insulated door as illustrated in Figure 4, I provide insulating sheets 2 which fill the space between cleats 26 and have the same thickness as these cleats.

Thus far it will be seen that I have provided a fully insulated panel of a door having a decorative front. I will now describe the frame of my improved door which is adapted to tightly embrace the four edges of the panel.

I preferably provide metal strips 28 and 29,

members 2S being under sheathing A and members 29 positioned on the rear side of sheathing I I. The purpose of these strips is to stiften the door transversely at the point where the hinges are attached (see Figure l). I provide Z irons 30, 3l, 32 and 33 as clearly indicated in Figures 4, 5 and 6, the depths being slightly greater than the thickness of the panel.

I provide front plates 34, 35, 3b and 31, each preferably attached to their respective Z irons as follows: Plate 3l is folded over the outwardly extending lip of member 33 as at 38, the inner edge being bent or folded back as at til, a space being left between the fold for bar lili thus it will be seen that a U shaped frame bar is formed which will tightly embrace the panel, leaving an air space as at lll. Plates 34, 35 and Sii are formed and attached to their respective Z irons exactly as in plate 3l. The ends of the U shaped frame bars thus formed are mitered as at l2 (see Figure l), thus to form the three sides of the door frame. rIhe bottom plate 3d is made quite wide, the top edge terminating preferably as at i8, thus to act asa flashing plate, the bottom edge being folded over the outwardly projecting flange of member Si! as at 53.

By referring to Figure fl it will be seen that flashing plate 3d is bent as at 5i and 52 thus to contact the strip iii near its bottom and continue upward in contact with the insulating sheet 2i, rivets 53 acting to hold memberA and the hashing plate it into position.

It will be seen by referring to Figure l that plates 35 and 36 are not mitered at their bottom ends but extend to the bottom of member A as illustrated, Z iron @il at its ends however, being mitered to the ends of members 32 and 3l. The U shaped frame bars, as described and illustrated, are preferably rst completed, then pressed over the panel edges and the mitered ends welded together, thus to form a substantial frame for the panel, the sides and top being securely bound to the panel by means oi suitable rivets 55, the bar it answering as a spacer for the inner folds of the side and top plates. Other bolts and rivets are provided as illustrated in the various gures.

By referring to Figure i, it will be noted that I provide preferably a number of spaced rivets These rivets act to hold the bottom edge of member A tightly against the bottom of member 3d.

Thus it will be seen that I have provided a strong, iron clad, fully insulated door. In Figure 6 it will be noted that I have leit out insulating member 2i. In this design I preferably supply vertical wood strips 5l' which are the same width and thickness as strips E@ and long enough to ll the space between these strips; thus there will be left a dead air space between the strips 26 and 5l'.

Thus it will be seen that I provide numerous vertical air pockets which are open at their bottoms under sheathing A; that there is an air space 22 between member A and flashing til; that an air channel il is provided which intersects the narrow air space at the edges of the panel; and that orifices 58 in member 3d provide a drip outlet for any moisture that might accumulate around the spacer members.

Clearly many minor changes in the shape and manner of securing the parts together may be made without departing from the spirit and scope of the appended claims.
